US Secretary of State Antony Blinken has arrived in Kyiv as part of an international bid to show solidarity with Ukraine amid fears over Russia's military movements.

The visit comes amid soaring tensions between Washington and Moscow over a possible Russian invasion of pro-Western Ukraine as tens of thousands of Russian troops amass on Ukraine's borders.

Blinken is scheduled to meet President Volodymyr Zelenskyy and his counterpart Dmytro Kuleba in the Ukrainian capital later on Wednesday.

What did Blinken say?

Speaking at the US Embassy in Kyiv shortly after his arrival, Blinken emphasized that his visit is intended to reaffirm the United States' commitment to Ukraine's sovereignty and territorial integrity.
